Hi, I'm helping my brother in law out with an inground pool. They just bought the house over the winter and are now in possession of a 16x32 inground pool with a vinyl liner, an Older Hayward Perflex 65 DE filter and Hayward pump. The pool hadn't been used in at least 5 years and was never covered. There were frogs in it and was very dark green.

We were able to get everything hooked up and the pump and filter appear to be working. We scooped out as much muck from the bottom as we could with a leaf bag, added 10 gallons of liquid chlorine, and couple packs of shock and ran the filter. The water lightened up a bit, but not much better. We have been trying to run the filter as much as possible but after an hour it gets pretty clogged to the point of very low return flow, so we have to bump and recoat very often. There is no one at the house during the day, so the pump is only run for a few hours every night. Does anyone have any recommendations to get this pool cleaned up as soon as possible?
